Sodium Dichloroisocyanurate

Sodium Dichloroisocyanurate (CAS Number:2893-78-9) Supplier in Europe

Sodium Dichloroisocyanurate (SDIC) is an important chemical agent widely adopted for its disinfecting properties. It is an effective source of chlorine and is utilized for sanitizing swimming pools and potable water, as well as for surface disinfection in various industries.

The compound comes in granular or tablet form. It is known for its high solubility in water, which allows for a rapid and even release of disinfectant agent when dissolved.

In water treatment, SDIC plays a pivotal role in ensuring the safety of drinking water by eliminating potentially harmful microorganisms. Its chlorine-releasing capacity helps to neutralize pathogenic bacteria, viruses, and protozoa, making the water safe for human consumption.

In comparison to liquid bleach, SDIC offers a prolonged shelf life and does not degrade substantially in storage, making it a convenient option for both large-scale and household water purification needs.

The use of SDIC extends beyond just water purification; it is also employed in various hygiene applications.

Healthcare facilities, for instance, utilize SDIC for infection control measures, specifically for disinfecting surfaces, equipment, and hospital environments. Its wide-ranging efficacy against a variety of pathogens makes it a reliable choice for maintaining high standards of cleanliness and preventing the spread of disease.

Chemical Properties and Synthesis

Sodium Dichloroisocyanurate, with the formula C3Cl2N3NaO3, plays a pivotal role in various applications due to its chemical properties and the synthesis process which affects its purity and effectiveness as a biocide.

Molekulare Struktur

Sodium Dichloroisocyanurate (CAS number: 2893-78-9) exhibits a molecular structure where sodium, chlorine, nitrogen, and oxygen atoms form a complex ring known as triazine.

Synthesis and Commercial Forms

Sodium Dichloroisocyanurate is synthesized through the chlorination of cyanuric acid with sodium hydroxide, resulting in a sodium salt form, which integrates effectively into water treatment processes.

It is available commercially in various forms, including tablets, granules, and powder, each labeled with a unique Lot/Batch Number for traceability and quality control, supported by a CoA (Certificate of Analysis) from the manufacturer.

Mechanism of Action

Upon dissolution, Sodium Dichloroisocyanurate releases Hypochlorous Acid and Cyanuric Acid, exerting its biocidal properties by forming Free Available Chlorine, which disrupts the cellular mechanism of microorganisms.

The amount of Free Available Chlorine determines the potency and effectiveness of the biocide, with the degradation to Wasserstoff gas occurring at a minimal level. The mechanism ensures a sustained release of chlorine, enhancing the longevity of its disinfection capacity in water treatment and other sanitization applications.

Applications and Guidelines

Sodium Dichloroisocyanurate (NADCC) is a widely used disinfectant known for its effectiveness against viruses and other pathogens. It is pivotal in various sanitation and hygiene practices, especially in water treatment and surface disinfection, guided by stringent safety and environmental protocols.

Disinfection Processes

NADCC plays a crucial role in the control of infectious diseases by acting as a potent disinfectant. It is commonly used for the sanitation of surfaces in healthcare settings and households.

The chemical’s efficacy against a broad spectrum of microorganisms includes most viruses, making it essential for maintaining hygiene standards. For effective use, surfaces must be pre-cleaned of any organic matter to ensure proper disinfection.

Usage in Water Treatment

In the context of water treatment, NADCC has been pivotal in drinking-water chlorination to ensure safe consumption.

• Chlorination Procedure for Drinking-Water:
  • Initial dosage: Determined by water volume and contamination level.
  • Maintenance: Regular monitoring and reapplication to maintain residual disinfectant levels.
  • Distribution: NADCC tablets are often distributed in emergency and resource-limited settings, thanks to their ease of handling and storage.

The World Health Organization (WHO) includes NADCC in the “Guidelines for Drinking-Water Quality,” highlighting the randomized evaluation of its impact on waterborne diseases, and encourages adherence to these standards for improved health outcomes.

Safety and Environmental Concerns

While NADCC is an effective disinfectant, care must be taken to use it properly to avoid hazardous outcomes.

In swimming pools, failure to maintain the correct dosage can lead to irritation of the skin and eyes or the production of undesirable by-products in the air.

Regarding safety, proper storage and handling guidelines should always be followed:

• Storage guidelines: Keep in a cool, dry place away from direct sunlight and incompatible substances.
• Handling procedures: Use personal protective equipment and avoid inhalation or direct contact with the skin.

The environmental impact of NADCC is generally considered to be low when used correctly, but it is still essential to conduct an evaluation of its effects on local ecosystems, especially when used in large quantities.
